HTML Specify Length and Width of Square Grid Picture System - html

Question

I have a square grid. I would like to make the size of the pictures smaller by specifying measurement, while retaining the 2x2 shape, or 3x3 shape etc. Tried setting the width property but did not work. Currently its too big.
How would I resolve this?

This is one way in CSS, looking for Bootstrap way, using grid-template-columns

grid-gap: 0em;
padding: 0px;
}
img {
width: 100%;
height: auto;
padding:0px;
}
HTML:
<div class="grid-container">
<img src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/210284/san-fransisco-768x432.jpg" alt="san francisco">
